Little mini product review on those felt polishing wheels I got from China. They're very good! Same diameter but much thicker than the last lot I got off eBay from a UK seller. But more importantly they're denser, so they're tougher, do the job quicker and last longer. Only negative so far, and this is just a case of getting used to them, but I did rip them off the mandrel by pressing too hard. Solution was to switch from the screw-on mandrel to one with a fixing nut that holds the wheels on tight.
